Abstract

A display panel includes a substrate including a corner display area including a strip portion between cut portions; and corner pixels in the strip portion and corner pixel circuits which drives the corner pixels, wherein each of the corner pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, and each of the corner pixel circuits includes a first pixel circuit which drives the first sub-pixel, a second pixel circuit which drives the second sub-pixel, and a third pixel circuit which drives the third sub-pixel, and the first pixel circuit, the second pixel circuit, and the third pixel circuit included in an n-th corner pixel circuit in a first direction that is a lengthwise direction of the strip portion are arranged differently from the first pixel circuit, the second pixel circuit, and the third pixel circuit in an (n+1)-th corner pixel circuit.

Claims (49)

1. A display panel comprising:

a substrate including a first display area and a second display area;

first pixels on the substrate in the first display area;

first pixel circuits on the substrate in the first display area, wherein the first pixel circuits drive the first pixels; and

second pixels on the substrate in the second display area; and

second pixel circuits on the substrate in the second display area, wherein the second pixel circuits drive the second pixels,

wherein

each of the second pixels includes a 2-1st sub-pixel, a 2-2nd sub-pixel, and a 2-3rd sub-pixel,

each of the second pixel circuits includes a 2-1st pixel circuit which drives the 2-1st sub-pixel, a 2-2nd pixel circuit which drives the 2-2nd sub-pixel, and a 2-3rd pixel circuit which drives the 2-3rd sub-pixel, and

an arrangement of the 2-1st pixel circuit, the 2-2nd pixel circuit and the 2-3rd pixel circuit in an n-th second pixel circuit in a first direction is different from an arrangement of the 2-1st pixel circuit, the 2-2nd pixel circuit and the 2-3rd pixel circuit in an (n+1)-th second pixel circuit in the first direction, wherein n is a natural number.

2. The display panel of claim 1 , wherein

the 2-1st pixel circuits and the 2-3rd pixel circuits are alternately arranged in a first column which extends in the first direction, and

the 2-2nd pixel circuits are arranged in a second column which is adjacent to the first column.

3. The display panel of claim 1 , wherein the 2-1st pixel circuit overlaps at least two of the 2-1st sub-pixel, the 2-2nd sub-pixel, and the 2-3rd sub-pixel.

4. The display panel of claim 1 , wherein the 2-2nd pixel circuit overlaps the 2-1st sub-pixel, the 2-2nd sub-pixel, and the 2-3rd sub-pixel.

5. The display panel of claim 1 , wherein an arrangement of the first pixels is different from an arrangement of the second pixels.

6. The display panel of claim 1 , further comprising signal lines disposed extending in the first direction outside the second pixel circuit.

7. The display panel of claim 6 , wherein

the signal lines transfers scan signals, and

some of the signal lines are connected to the n-th second pixel circuit and the (n+1)-th second pixel circuit.

8. The display panel of claim 6 , wherein a data line, which transfers data signals to the second pixel circuits, overlaps the second pixel circuits and extends in the first direction.

9. The display panel of claim 1 , wherein the 2-1st sub-pixel, the 2-2nd sub-pixel, and the 2-3rd sub-pixel are red pixel, green pixel, and blue pixel, respectively.

10. The display panel of claim 1 , wherein the second display area includes a curved portion.

11. A display apparatus comprising:

a display panel including a first display area and a second display area; and

a cover window covering the display panel,

the display panel comprising:
